I wouldn't necessarily call Frankenweenie a "Disney" movie. Mostly a Tim Burton film. By the way, I haven't watched it yet, so I don't know if it's any good.
And, I think Disney has both risen and fallen at the same time. They still make good movies sometimes. Like Wreck-It Ralph, The Princess and the Frog, and so forth. But I'll agree that they aren't the Disney they used to be. And they really are whoring themselves out too much...especially when Lucasfilms sold itself to them.
